A connection passage is formed by a first impeller housing member, a motor housing member, and a second impeller housing member. This prevents, for example, the formation of a gap between a housing and a pipe, which is separate from the housing, in a centrifugal compressor like in a configuration in which a first discharge port and a second suction port are connected to each other by attaching the pipe to the housing. The connection passage is formed only by sequentially overlapping and coupling the first impeller housing member, the motor housing member, and the second impeller housing member with each other in an axial direction of the rotary shaft. This eliminates, for example, the need to provide a structure in the pipe that absorbs the dimensional tolerances that occur between the housing and the pipe when attaching the pipe to the housing.

A control circuit performs at least one of a first phase shift control and a second phase shift control. The first phase shift control outputs a primary-side control signal so that a positive voltage is applied to a primary-side winding, and then outputs a secondary-side control signal so that a positive voltage is applied to a secondary-side winding when the voltage of the capacitor is higher than a battery voltage primary-side conversion value during activation of a bidirectional DC/DC. The second phase shift control outputs the secondary-side control signal so that a positive voltage is applied to the secondary-side winding, and then outputs the primary-side control signal so that a positive voltage is applied to the primary-side winding.

A combustor includes a combustion pipe, a gas introduction pipe, and an igniter. The gas introduction pipe is connected at one end of the gas introduction pipe to the combustion pipe, and the one end has a gas outlet through which ammonia and oxidized gas flow to the combustion pipe. The gas introduction pipe protrudes toward an inside of the combustion pipe through an insertion hole of the combustion pipe in a tangential direction to an inner peripheral surface of the combustion pipe so that the gas outlet is accommodated in the combustion pipe. The gas introduction pipe has a cross-sectional area that is defined so that mixed gas of the ammonia and the oxidized gas flows to the combustion pipe through the gas outlet at a flow velocity of 3 m/s to 25 m/s relative to a flow rate of the mixed gas.

RESTRAINT JIG AND METHOD FOR MANUFACTURING POWER STORAGE MODULE
A first unit includes a pair of restraint members disposed at both ends in the Z-axis direction of the electrode laminate, and a pair of regulation members disposed at both ends in the Y-axis direction of a held body including the electrode laminate and the pair of restraint members. Each regulation member includes a pair of contact parts brought into contact with respective edges of the restraint members from an outer side in the Z-axis direction, and a connection part connecting the contact parts. A size of the connection part in the X-axis direction is equal to or larger than a size of the electrode laminate in the X-direction. Relative positions of the regulation members with respect to the restraint members are fixed by insertion members inserted into through holes of the restraint members and the contact parts.
A restraining jig includes: a first unit configured to apply a restraining load in the Z-axis direction to an electrode laminate via a pair of restraint members disposed at both ends in the Z-axis direction of the electrode laminate; and a second unit including a flow channel part communicating with a space by being connected to an opening, and a base part supporting the flow channel part. The second unit is disposed to be freely attached to or detached from the first unit. When the base part is fixed to at least one of the pair of restraint members by fixing parts configured to regulate movement in the X-axis direction of the second unit with respect to the first unit and fix the second unit, the flow channel part is liquid-tightly connected to the opening.

A mobile unit control system includes an image capturing device and processing circuitry. The image capturing device is a stereo camera unit. The processing circuitry acquires image data from the image capturing device. The processing circuitry detects a marker from the image data. The processing circuitry estimates a position of the mobile unit in the movement environment from a positional relationship between the mobile unit and the marker based on the marker. The processing circuitry executes a control based on the position of the mobile unit.
A motor drive device includes a motor having a rotor, and a control device that controls the motor. The control device calculates a first value based on a d axis current and a q axis current of the motor. The control device calculates a second value by integrating the first value. The control device calculates a third value by performing prescribed control for making the second value equal to zero. The control device performs, based on the third value, position control for causing a rotational position of the rotor to match a designated position.

A power converter includes a charger, a battery, a motor, an inrush current limiter, and processing circuitry. A first switching unit connects the charger to the battery. A second switching unit connects a positive conductor to the neutral point of the motor. A third switching unit connects the battery and the inverter. The inrush current limiter is connected in parallel to the third switching unit and includes a resistance element and a fourth switching unit. The controller pre-charges a second capacitor arranged between the battery and the inverter by turning off the third switching unit and turning on the fourth switching unit.
